In a crystal of calcium, the type of bond between calcium is metallic bond. Metallic bond is the force of attraction between positively charged metallic ion and negatively charged sea of delocalised electrons. Answer verified by Toppr Upvote (0) Was this answer

Calcium Metal - an overview | ScienceDirect Topics

The production process of calcium metal by the metallothermic reduction process (see Equation 2.9.43) is shown in Figure 2.9.43. The raw material CaCO 3 is calcined to produce CaO. Low magnesia content (MgO) is preferred for the reduction feed materials because magnesia is preferentially reduced in this process, thus lowering the reaction efficiency for calcium metal.
